Recording LPs via a USB turntable

Audacity Help Forum Windows

I have a Stanton T.90 USB turntable and am trying to record from an LP to Audacity (audacity-win-2.0.2.exe) running on Windows 7. Dell Laptop 6 months old.

There is a fairly high-pitched undertone when I select ‘Record’. This is not loud but is unwanted. I’ve used different USB cables, USB 2 and USB 3 ports (much worse on USB3), moved the turntable some 6/7 feet from the computer, removed the cartridge from the tone-arm in case that was the problem (‘recording’ without making contact with the LP itself). I’ve reinstalled the turntable. There is still that unwanted pitch. The screen shot of the main Audacity display shows all the correct settings in accordance with the manual.

I have to set the sound input level to almost zero via the Windows system because the input level is too high and there is a lot of clipping., thus the slider on the Audacity program is locked at zero.

Have you any advice please?

High pitched interference can be caused by laptop power supplies.
Try making a recording with the laptop running on batteries and see if that is any better.

OK Steve, thanks. I’ll try that.
